No, it’s not recommended to run the i3 12100f above 90°C with stock cooler during unpacking.

Ensured sufficient thermal paste application. Verified connection between IHS and cooler.
Yeah, I'd check and make sure you didn't forget some plastic foil between the cpu and the heatsink, and that there's thermal paste between cpu and heatsink. While you're there, make sure the cooler is tight, that there is some pressure on the cpu, and it's not loose just standing in place due to the retention clips/legs There may be a bios option, something related to fan curves, maybe in bios you have the cpu fan set to "silent" or something like that, in which case the fan normally runs at lower speeds so the heatsink will be warmer most of the time, and when you start doing something very cpu intensive, it would take much less time for the cooler temperature to rise to 90-100. If that's the case, you could try to adjust that fan curve to keep the fan at higher speed all the time, and to spin up the fan much faster when the temperature increases.
I have the 12400, I used the stock cooler for a bit, when stress testing for half an hour with Cinebench, max temp was 88C. There's definitely an issue with your cooler. Re-seat the cooler, I'm sure that either the mounting pressure is not proper, or thermal paste wasn't enough/not applied properly.
I believe the power is around 60 watts (I use the base frequency boost from ASRock). The temperatures decrease for about half a minute when lowering from 90 to 60 (probably thermal throttling, not sure). I think it doesn't really affect things during that unpacking session.
